Dayton Audio 6.8µF Capacitor 1% Tolerance

Description

Product Overview

The Dayton Audio PMPC‑6.8 is a premium 6.8 µF film capacitor engineered specifically for audio crossover applications. With a tight tolerance of ±1 % and a maximum voltage rating of 250 VDC, it provides the stability and precision required for high‑end speaker designs. Constructed from high‑quality polypropylene film, the capacitor offers low dielectric loss, ensuring minimal signal degradation across the audible spectrum. Its extra‑thick tinned copper leads are designed for durability and easy soldering, while the compact 18 mm × 45 mm (0.71 in × 1.77 in) footprint fits comfortably in most crossover chambers. Weighing only 0.32 oz, the component adds negligible mass, preserving the acoustic integrity of the enclosure.

Usage

This capacitor is ideal for both DIY enthusiasts and professional audio engineers building or upgrading two‑way, three‑way, or even more complex speaker systems. It excels in high‑current environments such as mid‑range and tweeter networks where precise capacitance values are critical for achieving the intended crossover slopes. Install the PMPC‑6.8 in sealed or vented enclosures, ensuring the leads are trimmed to the appropriate length for a clean solder joint. The component’s 250 V rating provides ample headroom for most automotive and home‑theater amplifiers, making it a versatile choice for a wide range of power levels.

Why Choose Us

Dayton Audio has a long-standing reputation for delivering reliable audio components, and the PMPC‑6.8 is no exception. Each capacitor undergoes rigorous testing to verify its tolerance, voltage rating, and long‑term stability, ensuring that you receive a product that meets exacting industry standards. The use of extra‑thick tinned copper leads reduces the risk of lead fatigue and improves solderability, which translates to a more secure and lasting connection. Additionally, the capacitor’s low ESR (Equivalent Series Resistance) contributes to reduced heat buildup, extending the lifespan of both the component and the surrounding circuitry.

FAQ

What does a 1% tolerance mean for my crossover design?

A 1% tolerance indicates that the actual capacitance value will vary by no more than ±1 % from the nominal 6.8 µF. This precision helps maintain the intended crossover frequency and slope, resulting in more accurate sound reproduction.

Can this capacitor be used in automotive audio systems?

Yes. The 250 V rating provides sufficient voltage headroom for most automotive amplifiers, and the robust lead construction withstands the vibration and temperature variations typical in vehicle environments.

Is the capacitor polarized?

No. The PMPC‑6.8 is a non‑polarized film capacitor, allowing it to be installed in either direction without concern for polarity.

How do I ensure a reliable solder joint?

Trim the leads to a length that allows a comfortable solder pad exposure, clean the pads with isopropyl alcohol, and use a soldering iron set to around 350 °C. The extra‑thick tinned copper leads melt easily, forming a strong mechanical and electrical connection.

What is the expected lifespan of this capacitor?

When operated within its specified voltage and temperature limits, the capacitor is rated for a service life of 10 years or more, maintaining its capacitance and low loss characteristics throughout.
