## Description

The ECS Inc. International ZTB455E is a 455 kHz piezoelectric ceramic resonator designed for through-hole PCB mounting within legacy timing and clock generation circuits. Operating at a nominal frequency of 455.0 kHz with an initial frequency tolerance of ±2% at +25°C, this 2-pin component provides a stable frequency reference utilizing lead zirconate titanate (PZT) ceramic material. It features a frequency stability of ±0.3% across an extended operating temperature range of -20°C to +80°C, a maximum equivalent series resistance (ESR) of 20 ohms, and a 10-year aging characteristic of ±0.5%.

This low-frequency ceramic resonator is typically deployed in standard local oscillators, microcontroller clock circuits, remote controls, and communication receivers requiring moderate frequency precision without external capacitors. The component specifies built-in load capacitance values (C1 and C2) of 100 pF. Thermal parameters include a storage temperature range of -20°C to +85°C and a wave-solder profile tolerance with a maximum peak solder temperature of +230°C for up to 5 seconds, making it incompatible with standard surface-mount reflow processes.
