Ptc Resettable Fuses datasheet and documents for 0ZCH0075AF2E
Ptc Resettable Fuses Overview
The Bel Fuse 0ZCH0075AF2E is a surface-mount polymer PTC resettable fuse from the 0ZCH series, housed in a 1210 (3225 metric) package. It features a holding current of 750 mA and a trip current of 1.5 A. The device is rated for a maximum voltage of 24 VDC with an initial resistance of 400 Ohms. It operates within a temperature range of -40°C to +85°C and is classified as a slow blow fuse type.
Ptc Resettable Fuses Feature Summary
- Provides overcurrent protection through automatic resistance increase upon fault detection
- Enables circuit restoration without manual component replacement after cooling
- Designed for surface-mount assembly on printed circuit boards
Ptc Resettable Fuses Applications
- Portable electronic devices requiring compact circuit protection
- Consumer electronics circuits operating at low DC voltages
- Communication equipment input stages
Ptc Resettable Fuses Procurement Notes
Verify the specific suffix AF2E against official Bel Fuse documentation to confirm the exact voltage rating and package variant. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Ensure the procurement channel provides valid traceability documents matching the manufacturer's part identification.
Ptc Resettable Fuses Selection Notes
Select this component when a 1210 footprint is required for space-constrained designs. The 24 VDC rating suits low-voltage DC applications. Verify that the 750 mA holding current aligns with the normal operating load. Consider the 400 Ohm resistance impact on signal integrity or power loss in sensitive circuits compared to lower-resistance alternatives.
Ptc Resettable Fuses Part Context
This part belongs to the Bel Fuse 0ZCH series of SMT PTC fuses. The series offers various current ratings in the 1210 package size. It serves as a reusable alternative to traditional fusible resistors in modern electronics manufacturing.
Ptc Resettable Fuses Replacement Considerations
Check for direct substitutes within the 0ZCH series with identical 750 mA ratings. Verify pin compatibility and thermal characteristics before substituting with other manufacturers' 1210 PTC devices.
