Product Overview
Panasonic ECQ-B2274JF is a metallized polyester film capacitor rated at 0.27µF and 200VDC with ±5% tolerance. The ECQ-B series is known for stable analog performance and compact radial construction. The “274” marking corresponds to 270,000pF (0.27µF), and the “J” suffix confirms precision ±5% tolerance.
Designed as a self-healing film capacitor, it can clear localized dielectric breakdowns without catastrophic failure. This makes it suitable for signal coupling, timing networks, and filter circuits in audio, industrial, and control applications. The 200V rating provides headroom in higher-voltage analog stages and legacy equipment repairs.

Frequently Asked Questions
What does the 274J marking mean?
“274” represents 270,000 picofarads, which equals 0.27µF. The “J” indicates ±5% tolerance.
Is this capacitor polarized?
No. Metallized polyester film capacitors are non-polarized and can be installed in either orientation.
What is the voltage rating?
This unit is rated for 200V DC operation.
Is this suitable for audio signal paths?
Yes. Polyester film capacitors are widely used in analog audio circuits for coupling and filtering due to stable performance characteristics.
Are these in original packaging?
No retail packaging. These are bulk packed New Old Stock components.
Classic Panasonic film caps like the ECQ-B series defined many late-20th-century analog designs. If your board calls for a 0.27µF 200V film with tight tolerance, this one fits the footprint and the era.
