LT455HTW

Overview

The LT455HTW is a band pass ceramic filter manufactured by Transko Electronics, Inc. It operates at a center frequency of 455 kHz with a bandwidth of 2 kHz and an impedance of 2 kOhm. The component utilizes a cube package configuration featuring five PC pins for through-hole mounting.

Feature Summary

• Provides selective frequency filtering for AM radio receiver applications
• Utilizes a robust cube package design for mechanical stability
• Features five-pin PC lead configuration for standard circuit integration

Applications

• AM radio receiver intermediate frequency stages
• Selective frequency filtering in communication circuits
• Signal processing in broadcast equipment

Procurement Notes

Verify the specific part number LT455HTW against official Transko Electronics documentation to confirm the 2 kHz bandwidth and 2 kOhm impedance specifications. Ensure the five-pin PC pin package matches the target board layout requirements before procurement.

Selection Notes

Select this component when a narrow 2 kHz bandwidth is required for AM signal processing. The 2 kOhm impedance must match the source and load characteristics of the surrounding circuitry. The through-hole package dictates the assembly method and board space allocation.

Part Context

This component belongs to the LT series of ceramic filters from Transko Electronics. These devices are designed for reliable performance in intermediate frequency applications. The HTW suffix typically denotes the specific package style and termination type within the product line.

Replacement Considerations

Check for direct substitutes such as LTC455 variants or other 455 kHz ceramic filters with compatible 2 kHz bandwidth and 2 kOhm impedance. Verify package compatibility for the five-pin PC pin configuration before substitution.
