WCM2012F2SF-261T03

Overview

The WCM261T03 is a two-line surface mount common mode choke from the WCM2012F2SF series by TAI-TECH. It features an impedance of 260 Ohms at 100 MHz and a maximum current rating of 300 mA. The DC resistance (DCR) is specified at 400 mOhm, with a voltage rating of 50 V. The component operates within a temperature range of -40°C to +125°C. Its physical dimensions are 2.0 mm x 1.2 mm x 1.2 mm, utilizing wire wound technology for high-frequency noise suppression.

Feature Summary

• Realizes small size and low profile design suitable for space-constrained applications
• Provides high common mode impedance at high frequencies for effective noise suppression
• Manufactured using lead-free and halogen-free materials compliant with RoHS standards

Applications

• Common mode filtering in electronic circuits
• RF choke applications requiring compact form factors
• Noise suppression in portable devices due to thin profile

Procurement Notes

Verify the specific impedance value of 260 Ohms at 100 MHz against your circuit requirements. Confirm the 300 mA current rating is sufficient for your application's peak loads. Ensure the 400 mOhm DCR meets your power loss constraints. Check that the operating temperature range of -40°C to +125°C aligns with your environmental conditions. Validate the 50 V voltage rating for safety margins.

Selection Notes

Select this component when a compact 2.0x1.2mm footprint is required for EMI reduction. Choose based on the 260 Ohm impedance specification at 100 MHz for targeted frequency filtering. Consider the 300 mA current limit for low-power signal lines. The wire wound construction offers robust performance for common mode noise. Verify compatibility with surface mount assembly processes.

Part Context

This part belongs to the WCM2012F2SF series of wire wound type common mode filters. The series is characterized by its miniaturized 2.0x1.2x1.2 mm package and low profile. It is designed for surface mount technology applications. The manufacturer emphasizes compliance with environmental standards such as RoHS. The series targets applications needing efficient noise suppression in limited board space.

Replacement Considerations

Compatible substitutes include other parts from the WCM2012F2SF series with similar impedance ratings, such as WCM2012F2SF-221T03 or WCM2012F2SF-201T03. Ensure any replacement matches the 2.0x1.2x1.2 mm footprint and 300 mA current rating. Verify that the substitute maintains the same operating temperature range and RoHS compliance.
