Notes:
1. For details on electrical specifications, contact Littelfuse / Hamlin.
2. Contact Power Rating - Product of the switching voltage and current should never exceed this rating.
3. Operate (including Bounce) and Release Time - per EIA/NARM RS421A, diode suppressed coil.
4. Pull-In Range - Contact Littelfuse / Hamlin for tolerances available within this range.
5. Rating Sensitivity - The value at which contact ratings and operating characteristics are determined. Derating may be required below this value.
6. Storage Temperature - Long term exposure at elevated temperature may degrade solderability of leads.
