FB455K0000L112

Overview

The FB455K0000L112 is a ceramic filter manufactured by NextGen Components, designed for narrow-band filtering applications. It operates at a center frequency of 455 kHz with a bandwidth of 12.5 kHz and an impedance of 1.5 kOhm. The component features a maximum insertion loss of 6.0 dB and utilizes a through-hole mounting type. Its physical dimensions are specified as L11.0 mm x W7.0 mm x H8.0 mm in a cube package with 5 pins.

Feature Summary

• Provides narrow-band filtering capability suitable for communication circuits
• Utilizes a robust 5-pin cube package design for stable mounting
• Engineered for low insertion loss performance within the specified bandwidth

Applications

• Narrow-band filtering in receiver circuits
• Communication system signal processing
• Intermediate frequency (IF) filtering stages

Procurement Notes

Verify the specific datasheet version to confirm exact electrical tolerances and mechanical drawings before integration. Ensure compatibility with existing PCB footprint requirements for the 5-pin through-hole configuration. Cross-reference part numbers carefully as distributor listings may vary in suffix accuracy. Confirm RoHS compliance status if required by final assembly standards.

Selection Notes

Select this component when a 455 kHz center frequency with 12.5 kHz bandwidth is required. The 1.5 kOhm impedance matches standard circuit designs. Consider the through-hole package size for board space constraints. Compare insertion loss specifications against system sensitivity requirements to ensure adequate signal integrity.

Part Context

This part belongs to the FB series of KHz DIP ceramic filters from NextGen Components. It shares dimensional similarities with other models in the family but differs in electrical parameters such as bandwidth and center frequency. The series is characterized by its compact cube package and reliable performance in fixed-frequency applications.

Replacement Considerations

FB455K0000L010 is a documented alternative with similar dimensions but potentially different selectivity characteristics. Verify electrical parameter equivalence before substitution.
