ASCTB219E 201203-T1
TYPES
Standard packing: Carton: 20 pcs. Case: 200 pcs.
Note: Please use “CA
∗∗R-∗-∗-∗ or CA∗∗SR-∗-∗-∗” built-in resistor type. (Asterisks “ ∗ ” should be filled in from ORDERING INFORMATION.)
RATING
1. Coil data
Note: Other pick-up voltage types are also available. Please contact us for details.
2. Specifications
1) 12 V DC type
Notes: *1. This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the
actual load.
*2. The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Please refer to “Usage ambient
condition” in CAUTIONS FOR USE OF AUTOMOTIVE RELAYS.
