KEM10 Trimmer Capacitor Equivalent & Substitute Parts

Part Overview

The KEM10 is a 0.6–10pF trimmer capacitor rated for 125V operation with top-side adjustment and surface mount packaging. Manufactured by Knowles Voltronics, this component features an air dielectric, sealed construction, and operates across the temperature range of –65°C to 125°C. The KEM10 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the obsolete KEM10 is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance Range: 0.6–10pF (exact match required)
• Voltage Rating: 125V (exact match required)
• Adjustment Type: Top (exact match required)
• Dielectric Material: Air (exact match required)
• Q Factor: 5000 @ 100MHz (exact match required)
• Physical Dimensions: 0.230" Dia (5.84mm), Height 0.470" (11.94mm) (exact match required)
• Operating Temperature: –65°C to 125°C (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Construction: Sealed (exact match required)

The KM10 meets all specified parameters and is classified as an active product, providing direct functional and mechanical compatibility with the KEM10.

Parameter Comparison

Engineering Selection Recommendations

The KM10 is the direct active equivalent for the obsolete KEM10. Both components are manufactured by Knowles Voltronics and share identical electrical and mechanical specifications. The KM10 carries active product status and holds ROHS3 compliance and REACH unaffected certification, supporting modern procurement and regulatory requirements. Selection of the KM10 ensures functional continuity in applications requiring 0.6–10pF trimmer capacitors with 125V rating and top-side adjustment in surface mount configuration.
