Handling and Storage 2007.08.03 P0886EMDD03VOL01E • 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. © KEMET Electronics Corporation • P.O.

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: 30°C / 60% RH). If the relays have moisture absorption, dehumidify as follows: – Tape Packaging: 50 ±5°C, 200–300 hours. – Simple Relay: 85 ±5°C, 48 hours. 2. For MBB packing, please use relays within 2 years after delivery (storage conditions: 30°C / 60% RH). After opening MBB packing, please use within 3 months (storage conditions: 30°C / 60% RH). © KEMET Electronics Corporation • P.O.
