KEMET SH-211 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The KEMET SH-211 is a 2-line common mode choke designed for power line filtering applications. This through-hole component operates at 0.5 µH inductance at 100 kHz with a maximum current rating of 3A and DC resistance of 18 mOhm. The part is currently active in production with full RoHS3 compliance and REACH unaffected status. Substitute parts are identified to provide alternative options based on matching electrical and mechanical parameters within the SH series product line.

• Physical Dimensions: Within SH series envelope

The SH-211 substitutes are grouped within the KEMET SH series common mode choke family. All qualified substitutes maintain identical electrical ratings, compliance certifications, and mounting specifications while offering alternative inductance and resistance characteristics for specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

SH-211 Primary Application: The SH-211 operates at 0.5 µH inductance with 18 mOhm DC resistance. This configuration is suitable for applications requiring moderate filtering with acceptable resistive losses.

SH-101 Selection Criteria: The SH-101 provides lower inductance (0.35 µH) with reduced DC resistance (16 mOhm). Select this part when lower filtering inductance is acceptable and minimum resistive losses are required. Smaller physical dimensions (12.5mm x 10.00mm vs. 14.00mm x 12.00mm) may provide board layout advantages.

SH-201 Selection Criteria: The SH-201 matches the SH-211 inductance specification (0.5 µH) while offering reduced DC resistance (16 mOhm vs. 18 mOhm). This part provides identical filtering performance with lower power dissipation. Smaller physical dimensions align with the SH-101 envelope.

SH-202 Selection Criteria: The SH-202 provides higher inductance (1.5 µH) with slightly elevated DC resistance (20 mOhm). Select this part when increased filtering attenuation is required. Higher inductance delivers greater common mode noise suppression at the cost of increased resistive losses.

All substitute parts maintain active product status, full RoHS3 compliance, and identical electrical ratings (3A current, 150V DC voltage, -25°C to 80°C operating range). Selection between substitutes depends on specific inductance and resistance requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can SH-101, SH-201, and SH-202 be used interchangeably with SH-211?

A: These parts share identical current ratings (3A), voltage ratings (150V DC), operating temperature ranges (-25°C to 80°C), mounting types (through hole), and package configurations (vertical, 4 PC pin). However, they differ in inductance and DC resistance values. Interchangeability depends on whether the circuit design tolerates these parameter variations. The SH-201 provides the closest electrical match with identical inductance (0.5 µH) and lower resistance (16 mOhm).

Q: What is the difference between SH-211 and SH-201?

A: Both parts operate at 0.5 µH inductance at 100 kHz. The primary difference is DC resistance: SH-211 has 18 mOhm maximum while SH-201 has 16 mOhm maximum. The SH-201 exhibits lower power dissipation. Physical dimensions also differ: SH-211 measures 14.00mm x 12.00mm while SH-201 measures 12.5mm x 10.00mm.

Q: When should I select SH-101 instead of SH-211?

A: Select SH-101 when your circuit design requires lower inductance (0.35 µH vs. 0.5 µH) and can benefit from reduced DC resistance (16 mOhm vs. 18 mOhm). The SH-101 also provides a smaller footprint (12.5mm x 10.00mm), which may be advantageous for space-constrained board layouts.

Q: When should I select SH-202 instead of SH-211?

A: Select SH-202 when your application requires higher common mode filtering attenuation. The SH-202 provides 1.5 µH inductance compared to SH-211's 0.5 µH, delivering three times greater filtering inductance. Accept the trade-off of slightly higher DC resistance (20 mOhm vs. 18 mOhm) and increased power dissipation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts in this comparison—SH-211, SH-101, SH-201, and SH-202—are RoHS3 compliant and REACH unaffected. All maintain active product status with full manufacturing support.

Q: Do physical dimensions affect substitution compatibility?

A: Physical dimensions differ between parts but remain within the SH series envelope. SH-211 measures 14.00mm L x 12.00mm W x 9.50mm H. SH-101, SH-201, and SH-202 measure 12.5mm L x 10.00mm W x 12.00mm H. Verify board layout clearances before substitution, particularly for height variations.

Q: What inventory levels are available?

A: Current stock levels are: SH-211 (795 pcs), SH-101 (907 pcs), SH-201 (1774 pcs), and SH-202 (1067 pcs). All parts are new original stock in bulk packaging.
