CSTNR4M00GH5L000R0

The CSTNR4M00GH5L000R0 is a piezoelectric ceramic resonator from Murata, part of the CSTNR series, used for clock generation in microcomputers. It offers a nominal frequency of 4.0000 MHz with an initial frequency tolerance of ±0.07% and frequency stability of ±0.11% over the operating temperature range of -20°C to +85°C. Aging is specified at ±0.07% over 10 years equivalent at +25°C.

Electrical characteristics include a maximum resonant impedance of 60 Ω, built-in load capacitance of 39 pF ±20% (at 1 MHz), and insulation resistance of 500 MΩ minimum. The device operates with a DC voltage up to 6 V and an AC input signal up to 15 Vp-p. Withstanding voltage is 100 V DC for up to 5 seconds.

Mechanically, the resonator is housed in a 3-SMD, non-standard package with dimensions 4.5 mm x 2.0 mm x 1.1 mm. It features three terminals: Pin 1 (Input), Pin 2 (GND), and Pin 3 (Output). Mounting is surface mount, and packaging is tape and reel (TR). The operating temperature range is -20°C to +85°C, with storage from -55°C to +85°C.

This resonator is suitable for clock oscillator circuits in microcontrollers, consumer electronics, and industrial equipment requiring a stable frequency reference. It is marked as RoHS3 compliant (unverified) and has an MSL of 1 (unlimited floor life).
