Lite 04611.25ER SMD Time Delay Slow Blow Ceramic Fuse Tube LF1.25AT 1.25A 600V

Description

Lite 04611.25ER SMD Time Delay Slow Blow Ceramic Fuse Tube LF1.25AT 1.25A 600V

Product Description

The Lite 04611.25ER (also referenced as LF1.25AT) is a small form factor surface-mount, time-delay / slow-blow, ceramic fuse. It is designed to tolerate short-duration inrush currents and protect circuits from sustained overloads or fault currents. Its ceramic body provides high interrupting capacity and good thermal stability. It is commonly used in high-voltage, compact designs where protection against overcurrent is needed.

Key Features / Specifications

• Type: Time-delay (slow-blow) ceramic fuse

• Rating: 1.25 A (nominal current)

• Voltage rating: 600 V

• Form: SMD (surface-mount device) / ceramic tube body

• Delay characteristic: allows transient surges (inrush) without blowing immediately

• Breaking capacity / interrupt rating: (typical for ceramic fuses) high — often in the kiloampere range (verify in datasheet)

• Ambient operating temperature: typical fuse range (– some tens °C to ~125 °C or more)

• Body construction: ceramic (for high stability, arc containment)

• End-caps / electrodes: usually solderable metallized ends compatible with reflow processes

• Size / footprint: small — typically in “tube” style for SMD

• Compliance: likely RoHS / lead-free (depending on manufacturer)

Applications

• Overcurrent protection in high-voltage circuits

• Power supply front-end protection

• Protection for lighting, instrumentation, communication gear

• Inrush-laden circuits (motors, LEDs, capacitive loads) where transient tolerance is needed

• Industrial electronics, energy systems, or battery backup systems

• Any circuit requiring compact, high-voltage slow-blow protection
