The 383 series in its compact TR5® package provide an ideal alternative over glass cartridge fuses in electronic ballast application, especially where PCB board space is limited.
The 383 series radial leaded fuses are rated at 300VAC as compared to existing competition in the market which are rated at 250VAC.
In addition, it can either be directly soldered or used in conjunction with plug-in holder. And its Tape and Ammo-packaging are ideal for high volume production.
- Offer adequate circuit protection at high operating voltage
- Help to optimize the use of limited PCB board space
- UL and CSA agency approval
