ED2/EF2 Series

Miniature Signal Relays
ED2/EF2 Series
Overview
Applications
The KEMET ED2/EF2 miniature signal relays offer a 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.

• If any material containing silicon (silicon rubber, silicon oil, and silicon based coating material) is used in the neighborhood of
relay, there is some possibility that these materials will emit silicon gas that will penetrate the relay. In this case, the switching

use of relay in such an environment.

5. 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.

Miniature Signal Relays – ED2/EF2 Series
Notes on Using Relays cont’d
• 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: 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).
