1 / 7 page TX RELAYS 2 A CAPACITY RELAY WITH HIGH SURGE VOLTAGE & HIGH BREAKDOWN VOLTAGE TESTING mm inch 8.2 .323 7.4 .291 15 .591 8.4 .331 7.4 .291 15 .591 FEATURES • Breakdown voltage between contacts and coil: 2,000 V • Surge withstand between contacts and coil: 2,500 V • High contact capacity: 2 A 30 V DC • Surface-mount type available SPECIFICATIONS Contact Notes: ❇1This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the ac- tual load. (SX relays are available for low level load switching [10 µA 1 mV DC – 10 mA 10 V DC]) ❇2The upper limit for the ambient temperature is the maximum temperature that can satisfy the coil temperature rise. Under the packing condition, allowable tem- perature range is from –40 to +70°C –40°C to +158°F. Remarks * Specifications will vary with foreign standards certification ratings. *1 Measurement at same location as "Initial breakdown voltage" section. *2 By resistive method, nominal voltage applied to the coil; contact carrying current: 2 A. *3 Nominal voltage applied to the coil, excluding contact bounce time. *4 Nominal voltage applied to the coil, excluding contact bounce time without diode. *5 Half-wave pulse of sine wave: 6 ms; detection time: 10 µs. *6 Half-wave pulse of sine wave: 6 ms. *7 Detection time: 10 µs. *8 Refer to 6.
