CZ-38 Series
Small-sized, High Accuracy, SMD
Coreless Current Sensor ICs
supporting operation up to 125℃
CZ-3813, CZ-3814, CZ-3815
The market has been recently demanding more small-sized systems, dustproof, and waterproof structures. Small bodies, lower heat generation and high temperature operation range is required for current sensors.
The CZ-38 series has a miniaturized body while maintaining a low-heat generation characteristic, supporting up to 125℃ operation temperature.
It is suitable for systems having difficulty in temperature design and applications that use large current.
Applications
- AC motors
- DC motors
- UPS's
- Power conditioner (DC side)
- Air conditioner
It is suitable for the application which requires insulation and small size with low heat generation.
Features
Supporting 125°C and 40Arms
The CZ-38 series supports up to 125 °C operation temperature by suppressing heat generation with an originally developed AKM package.
This enables 40Arms continuous current, making the CZ-38 usable even in the current range where conventional current sensors with a core are required.
Therefore, downsizing existing system is possible.
High Accuracy
The CZ-38 series is a highly accurate coreless current sensor with 0.7% F.S. (Typical).
This will contribute to improving system efficiency and precise control in a wide range of application.
Small-sized
The CZ-38 series achieves this size using a coreless structure AKM’s developed original package.
The package size is 6.7 x 8.3 x 2.0 (mm), which is about 1/20 of the volume of our conventional products.
