概述

Description

I can’t locate public information for PKM13EPYH4002-B0, so I can’t give a precise introduction yet. If you can share the manufacturer, a datasheet link, or more context (e.g., is it an IC, sensor, connector, module?), I’ll summarize accurately.
In general, an intro would cover:
- Product category and function
- Key specs (operating voltage/current, interfaces, package)
- Notable features (ratings, protocols, pinout)
- Typical applications
- Availability and where to source

Package

PKM13EPYH4002-B0 is a 13 mm disc-type piezoelectric transducer element (flat ceramic disk). It's the bare piezo element package used for sound generation (not a boxed buzzer).

Pinout

Pin count: 2 (two terminals: positive and negative).
Function: Piezoelectric sound transducer (buzzer/element) — converts electrical drive signal into audible sound. Typically a passive piezo element requiring an external drive signal (AC or oscillated DC).

Manufacturer

Manufacturer: Murata Manufacturing Co., Ltd.
What kind of company: Murata is a Japanese multinational, publicly traded electronic components manufacturer specializing in passive components, sensors, timing devices, wireless modules and piezoelectric products (including buzzer elements like the PKM13EPYH4002‑B0), serving consumer electronics, automotive, industrial and medical markets.

Equivalent

PKM13EPYH4002-B0 is a 13 mm piezoelectric disc transducer. Equivalent parts are other 13 mm, ~4.0 kHz piezo discs with the same mechanical/electrical specs, for example:
- Murata PKM13EPYH4000-series (other suffixes)
- CUI Devices 13 mm piezo elements (CPE/CMT-13 family)
- TDK 13 mm piezo discs
Always confirm resonant frequency, capacitance, thickness and mounting before substituting.
