Overview
The CM1210B104R-1A is a surface-mount common mode choke from the Laird CM Series, designed for automotive signal line applications. It features a 10 µH inductance at 100 kHz and provides 5.1 kΩ impedance at 10 MHz. The component supports a rated current of 150 mA with a maximum DC resistance of 1.5 Ω. Housed in a 1210 (3225 metric) package, it measures 3.20 mm in length and 2.50 mm in width. This two-line filter is RoHS compliant and suitable for high-reliability environments.
Feature Summary
- Dual-line filtering architecture for effective noise suppression on paired signal traces
- Optimized for automotive signal integrity to enhance system reliability
- Compact surface-mount footprint facilitates automated PCB assembly
Applications
- Automotive signal line EMI filtering
- High-reliability electronic circuit protection
- Common mode noise suppression in data transmission lines
Procurement Notes
Verify the specific suffix and manufacturer designation when sourcing, as Laird-Signal Integrity Products components may have distinct ordering codes. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the selected variant matches the required 1210 package dimensions and electrical specifications for your design.
Selection Notes
Select this component for applications requiring robust common mode noise attenuation in compact spaces. The 150 mA rating suits low-current signal lines rather than power delivery. Consider the 5.1 kΩ impedance at 10 MHz for high-frequency interference mitigation. Verify that the 1.5 Ω DCR does not introduce excessive voltage drop in the target circuit.
Part Context
This part belongs to the Laird CM Series, specifically engineered for automotive signal lines. The series focuses on improving performance and reliability in demanding environments. The CM1210B104R-1A utilizes a 1210 case size, balancing filtering capability with board space constraints typical in modern automotive electronics.
Replacement Considerations
Publicly confirmed direct substitute part numbers are not available in the provided documentation. Evaluate other Laird CM Series variants or comparable automotive-grade common mode chokes based on impedance curves and current ratings.
