MOUNTING INSTRUCTIONS 1) Land Pattern Dimensions Large lands reduce Q of the mounted chip. Also, large protruding land areas (bordered by lines having dimensions 'c' and 'd' shown bellow) cause floating and electrode cracks. Solder Resist Land c d 12 2) Magnetic Coupling Since some chip coils are constructed like an open magnetic circuit, narrow spacing between coils may cause magnetic coupling. The LQH_R/S series have a magnetically shielded structure. The structure makes their coupling coefficient smaller than that of conventional chip coils. In particular, the LQH3ER series has a very small coupling coefficient.

The arrangement shown in Fig.2 is more effective in preventing stress than that shown in Fig.1. Fig.2 Fig.1 4) Amount of Solder Paste Excessive solder causes electrode corrosion, while insufficient solder causes low electrode bonding strength. Adjust the amount of solder paste so that solder is applied as shown in the right. Standard thickness of solder paste: 200m to 300m 5) Amount of Adhesive If too much adhesive is applied, then it may overflow into the land or termination areas and yield poor solderabillity. In contrast, if insufficient adhesive is applied, or if the adhesive is not sufficiently hardened, then the chip may become detached during flow soldering. Apply the adhesive in accordance with the following conditions.

Storage Period Products should be used within 12 months reckon from the date of our out-going inspection. Solderability should be verified if this period is exceeded. (LQH3ER/3KS series should be used within 6 months.) 2. Storage conditions a) Store products in a warehouse in compliance with the following conditions : Temperature : -10 to 40C. Humidity : 30 to 70% (relative humidity) Do not subject products to rapid changes in temperature and humidity. Do not store them in chemical atmosphere such as one containing sulfurous acid gas or alkaline gas. This will prevent electrode oxidation which causes poor solderability and possible corrosion of coils. b) Do not store products in bulk packaging to prevent collision among coils which causes core chipping and wire breakage. c) Store products on pallets to protect from humidity, dust, etc. d) Avoid heat shock, vibration, direct sunlight, etc. Notice (Soldering and Mounting) < CLEANING > The following conditions should be observed when cleaning chip coils. 1. Cleaning Temperature : 60C. max. (40C. max. for CFC alternatives and alcohol cleaning agents) 2. Ultrasonic Output : 20W/l max. Duration : 5 minutes max. Frequency : 28kHz to 40kHz Care should be taken not to cause resonance of the PCB and mounted products. 3. Cleaning agent The following cleaning agents have been tested on individual components. Evaluation in complete assembly should be done prior to production. a) CFC alternatives and alcohol cleaning agents * Isopropyl alcohol ( IPA ) 12 54 * HCFC-225 b) Aqueous cleaning agents * Surface active agent ( Clean Thru 750H ) * High grade alcohol ( Pine Alpha ST-100S ) * Hydrocarbon ( Techno Cleaner 335 ) * Alkaline Saponifier ( Aqua Cleaner 240 -cleaner should be diluted to 20% using deionized water. ) LQH_R/S series : Aqueous agents should not be used because they may cause quality deterioration. LQH series : Surface active agent and high grade alcohol can be used. 4. Ensure that flux residue is completely removed. Component should be thoroughly dried after aqueous agents have been removed with deionized water. For additional cleaning methods, please contact Murata. This is the PDF file of catalog No.O05E-6 O05E6.pdf 01.5.9 Notice Notice (Handling) This item is designed to have sufficient strength, but handle with care not to make it chipped or broken due to its ceramic structure. LQW_A series * Sharp material, such as tweezers, shall not touch to the winding portion to prevent the breaking of wire. * Do not give excessive Mechanical shock should not be applied to the products mounted on the board to prevent thebreaking of the core. * In some mounting machines,when picking up components,support pin pushes up the components from the bottom of base tape. In this case,please remove the support pin. The support pin may damage the components and break wire. LQH_C/D/H/M/N, LQW_H series * Sharp material, such as tweezers, shall not touch to the winding portion to prevent the breaking of wire. * Do not give excessive Mechanical shock should not be applied to the products mounted on the board to prevent thebreaking of the core. LQP series * The pattern of the chip coil is covered with the protection film. But the handling the chip coil shall be taken care so that the chip coil would not be damaged with the pick-up nozzle, the sharp substance and so on. LQM series * There is possibility that the inductance value change due to magnetism. Do not use a magnet or tweezers with magnetism when chip coil are handled. ( The tip of the tweezers should be molded with resin or pottery.) < HANDLING > 1. Avoid applying excessive stress to products to prevent damage. 2. Do not touch winding with sharp objects such as tweezers to prevent wire breakage. 3. Do not apply excessive force to products mounted on boards to prevent core breakage. < TRANSPORTATIONS > Do not apply excessive vibration or mechanical shock to products. < RESIN COATING > When coating products with resin, the relatively high resin curing stress may change inductance values. For exterior coating, select resin carefully so that electrical and mechanical performance of the product is not affected. 12 55 O05E6.pdf 01.5.9 This is the PDF file of catalog No.O05E-6 Packaging Minimum Quantity and 8mm Width Taping Dimension 8.00.3 (2.75) 3.50.05 4.00.1 <Paper> 1 0.2 4.00.1 b , ,,, a 1.750.1 <Plastic> 1.5 +0.1 -0 c c 2.00.1 Direction of feed LQW2BH 1 : 0.3 Paper Tape Part Number Dimensions (in mm) a b c 1.45 2.25 1.1 Minimum QTY.
