Three Sunlord MPHM series power chokes. According to my love audio network, the power inductor in the power circuit of wireless headphones needs to have a small size and medium size (hundreds of mA) rated current, and requires low loss of inductance to achieve high conversion efficiency and strong battery life.
The MPHM series has the following features:
1. For high-density placement circuits, MPHM series products show excellent anti-interference/anti-coupling and magnetic flux leakage performance;
2. The shape of the product is designed with Mark to mark the direction of magnetic flux, which can ensure that the direction of the magnetic field is consistent after the patch;
3. Excellent electrical performance such as large rated current, high reliability, DCR, etc.;
4. Meet the mainstream power requirements, adopt the stacking process, and provide customers with cost-effective products.

3. I love the audio network summary
EDIFIER W830NB over-ear noise cancelling headphones adopt a simple design in appearance, and at the same time, the structure is functional, the suspension supports left and right rotation, the ear shell supports small angle rotation up and down, and the telescopic head beam design can better adapt to different groups of people to wear; A folding function has also been added to improve portability. The ear cups and headrest are made of skin-friendly materials with soft padding on the inside for a very comfortable fit. However, due to the increase in weight due to factors such as the metal head beam, the long-term wearing comfort may not be as good as the previous generation.
The internal structure has also changed from the previous generation, except for the 40mm titanium-plated dynamic unit, the main configuration is located inside the right ear, and only two noise-canceling microphones are installed in the left ear. Three electret microphone units are built into the right ear for voice calls and noise cancellation function pickup; The built-in battery capacity is 670mAh, and it is equipped with a circuit protection board for charge and discharge protection.
On the motherboard, it is equipped with LPS microsource semiconductor LP4069T lithium battery charging IC for charging the built-in battery; BES BES2700H-6X Bluetooth audio SoC is used for wireless connection and audio data processing. The circuit is also equipped with a number of Sunlord Shunluo Electronics MPHM series power inductors, SDCL0603Q series laminated ceramic inductors and other components.
