TZ2965C

Crystals Overview

The TZ2965C is a surface-mount crystal resonator manufactured by TST, designed for high-precision frequency control in compact electronic systems. It operates at a fundamental frequency of 40 MHz with a frequency tolerance of ±7 ppm. The component features a load capacitance of 6 pF and an equivalent series resistance (ESR) of 20 Ohms. Packaged in a 4-SMD, no-lead footprint measuring 2.5 x 2.0 mm, it offers ultra-miniature dimensions suitable for mobile devices. This resonator provides stable oscillation characteristics required for wireless communication protocols including Bluetooth, WiFi, LTE, and GPS applications.

Crystals Procurement Notes

Verify the specific manufacturing date code and lot number against project requirements to ensure material traceability. Confirm that the 4-SMD no-lead package dimensions align precisely with the target PCB footprint to avoid soldering defects. Request manufacturer test reports or calibration certificates if strict frequency accuracy validation is mandated for the final assembly process.

Crystals Selection Notes

Select this component when space constraints are critical due to its small 2.5x2.0 mm form factor. Ensure the host circuit supports a 6 pF load capacitance to maintain the specified 40 MHz frequency. Consider the ±7 ppm tolerance sufficient for standard wireless interfaces like Bluetooth and WiFi where tight synchronization is not strictly required compared to higher-grade oscillators.

Crystals Part Context

This part belongs to the TZ series of crystal resonators from TST, which focuses on miniature solutions for consumer electronics. The series targets the growing demand for smaller components in smartphones and IoT devices. It serves as a passive frequency-determining element within oscillator circuits, replacing larger through-hole alternatives in modern surface-mount technology workflows.
