SPH0641LM4H-1 General Description

100 Hz ~ 10 kHz Digital, PDM Microphone MEMS (Silicon) 1.62 V ~ 3.6 V Omnidirectional (-26dB ±1dB @ 94dB SPL) Solder Pads

Key Features

Reliable contact
The contact has long dimples near the center to ensure a good connection at all times, even under conditions of vibration and mechanical abuse, and when used with low voltage and low current circuits.
Easy and effective crimping
Although the contact is compact, it has a long wire strip holding length of 2.6 +/- 0.4mm (.102" +/-.016"). This long length simplifies automatic crimping and the crimping of shielded wires.
Fully shrouded header
The fully shrouded header has walls on all four sides to prevent improper connection to the mating housing and to prevent the instruction of flux and other contaminants.
High solderable square post
The square post is copper-undercoated and tin/lead-plated for superior solderability and for whisker prevention.
Printed circuit board retention mechanism
The solder side of the header has a retention mechanism that prevents it from floating during soldering. As a result, the header can be positioned accurately.
Compatible with the KR insulation displacement connector
The same shrouded header can be used for either PH crimpstyle connector or KR insulation displacement connector. This allows both types of connector to be used interchangeably without replacing the header.
Surface mount model (SMT)
This connector is also available in a surface mount configuration. Its housing is made of heat resistant resin so that it is not adversely affected during reflow soldering.
Because of its tiny size and ability to be surface mounted, this connector meets the demand for high-density mounting of components inside electronic products.
