Miniature Signal Relays UA2/UB2 Series Overview Applications The KEMET UA2/UB2 miniature signal relays offer a super compact case size in a slim package. Minimal board space is consumed with either a through-hole or surface mount configuration. These relays are recognized by UL and CSA, while also being compliant with Part 68 of the FCC's 1,500 V surge capacity. * * * * Electronic switching systems PBX Terminal equipment Telephone systems Benefits * * * * * * * Low power consumption (< 140 mW) Super compact and lightweight Slim package for dense mounting Low magnetic interference Tube or embossed tape and reel packaging UL recognized (E73266) and CSA certified (LR46266) Surface mount and through-hole options Part Number System UB2- 3 S NU -L Series Coil Voltage Latch Type Lead Type Packaging UA2- = Through-hole mount 3 = 3 VDC UB2- = Surface mount 4.5 = 4.5 VDC 5 = 5 VDC 12 = 12 VDC 24 = 24 VDC Blank = Non-latch type S = Single coil latch type NU = Standard Blank = Tube NE = Low power consumption (Non-latch) -L = Embossed tape on reel NUN = Minimum footprint NEN = Low power consumption (Non-latch), Minimum footprint One world.

Handling and Storage * Relays are packaged in magazine cases for shipment. If a space is created in the case after some relays have been removed, be sure to insert a stopper to secure the remaining relays in the case. If relays are not well secured, vibration during transportation may cause malfunctioning of the contacts. * Exercise care in handling the relay so as to avoid dropping it or allowing it to fall. Do not use a relay that has been dropped. If a relay drops from a workbench to the floor, a shock of 9,800 m/s2 (1,000 G) or more is applied to the relay, possibly damaging its functions. Even if a light shock has been applied to the relay, thoroughly evaluate its operation before using it. * Latching relays are factory-set to reset state for shipment. A latching relay may be set, however, by vibration or shock applied while being transported. Be sure to forcibly reset the relay before using it in the application set. Also note that the relay may be set by unexpected vibration or shock when it is used in a portable set. * The sealability of a surface mount (SMT) relay may be lost if the relay absorbs and is then heated during soldering. When storing relays, therefore, observe the following points: 1. For standard packing, please use relays within 12 months after delivery (storage conditions: 30C/60% RH). If the relays have moisture absorption, dehumidify as follows: - Tape Packaging: 50 5C, 200-300 hours. - Simple Relay: 85 5C, 48 hours. 2. For MBB packing, please use relays within 2 years after delivery (storage conditions: 30C/60% RH). After opening MBB packing, please use within 3 months (storage conditions: 30C/60% RH).
