DATA SHEET MINIATURE SIGNAL RELAY EC2/EE2 SERIES RoHS Compliant COMPACT SIZE, SLIM-PACKAGE DESCRIPTION NEC TOKIN EC2/EE2 relay is a standard miniature signal relay, compact and slim. FEATURES Compact and light weight FCC (1500 V) and Telcordia (2500 V) surge capacity UL recognized and CSA certified. Low power consumption (100-200 mW) ND type (High insulation) conform to supplement insulation for EN60950 NKX type (High breakdown voltage) can withstand 1.5KVAC at open contacts APPLICATIONS Electronic switching systems, PBX, Terminal equipment, Telephone system For Right Use of Miniature Relays DO NOT EXCEED MAXIMUM RATINGS. Do not use relays under exceeding conditions such as over ambient temperature, over voltage and over current. Incorrect use could result in abnormal heating, damage to related parts or cause burning. READ CAUTIONS IN THE SELECTION GUIDE. Read the cautions described in NEC TOKIN's "Miniature Relays" when you choose relays for your application.

Keep the force applied to the relay to within 1 kg. - Avoid bending the pins to temporarily secure the relay to the PC board. Bending the pins may degrade sealability or adversely affect the internal mechanism. - It is recommended to solder the relay onto a PC board under the following conditions: <1> Reflow soldering Refer to the recommended soldering temperature profile. <2> Flow soldering Solder temperature: 260 max., Time: 5 seconds max. Preheating: 110~ 120 /110 sec. (max.) <3> Manual soldering Solder temperature: 350 , Time: 2~3 seconds - Ventilation immediately after soldering is recommended. Avoid immersing the relay in cleaning solvent immediately after soldering due to the danger of thermal shock being applied to the relay. - Use an alcohol-based or water-based cleaning solvent. Never use thinner and benzene because they may damage the relay housing. - Do not use ultrasonic cleaning because the vibration energy generated by the ultrasonic waves may cause the contacts to remain closed. 5. Handling - 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 transpor tation 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 the 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 moisture 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: 30 / 60% RH) If the relays have moisture absorption, dehumidify as follows. Tape packing: 50 5 , 200~300 hours. Simple relay: 85 5 , 48 hours. <2> For MBB packing, please use relays within 2 years after 17 All specifications in this catalog and production status of products are subject to change without notice.
