## **SMD Fuses**
## **Description**
The brick fuse for the small size and good electrical performance, reliability and quality. The solder-free design provides excellent on-off and temperature cycling characteristics during use and also makes our brick fuses more heat and shock tolerant than typical brick fuses.
## **Features**
- Fast Acting High current brick fuse
- Surface mount design to save space
- Ceramic Square body with end cap design
- Operating Temperature: -55°C to +125°C
- Storage Conditions: +10°C to +60°C
- Vibration Resistance: 24 cycles at 15 min. each (60068-6)
- Lead-free and Halogen-free
- Designed to UL248-1

Note:
- (1) AC Interrupting Rating (Measured at designated voltage, 100% power factor random closing)
(2) DC Interrupting Rating (Measured at designated voltage, time constant of less than 50 microseconds, battery source)
- (3) Typical Pre-arcing I[2] T are measured at 10In Current, DC battery bank, but not exceeding the interrupting rating, time constant of calibrated circuit less than 50 microseconds.
