Panasonic Electronic Components

<p>The Panasonic ECC-A3F390JGE is a high-voltage ceramic disc capacitor from the KGE series, offering a nominal capacitance of 39 pF with a tolerance of ±5%. It is rated for 3000 V DC operation and features an SL/GP temperature coefficient with a range of +350 to -1000 ppm/°C over 20 to 85 °C.</p><p>&nbsp;</p><p>This capacitor is designed for general-purpose high-voltage applications such as snubber circuits in switching power supplies, horizontal resonance circuitry for CRT displays, and inverter-type lighting ballasts. It provides a minimum Q factor of 1000 at 1 MHz and an insulation resistance of at least 10000 MΩ at 500 V DC.</p><p>&nbsp;</p><p>The component is housed in a radial disc package with a diameter of 7.00 mm and a seated height of 11.00 mm maximum. Lead spacing is 7.50 mm, and the leads are formed for easy through-hole mounting. The operating temperature range is -25 °C to 105 °C.</p>

<p>The Panasonic ECQ-E2224KS is a metallized polyester film capacitor with a capacitance of 0.22 µF and a voltage rating of 250 VDC. It offers a tolerance of ±10% and is designed for general purpose applications. The capacitor uses a metallized polyester dielectric, which provides self-healing properties and stable performance over time.</p><p>&nbsp;</p><p>This capacitor is housed in a radial through-hole package with a lead spacing of 15.00 mm and PC pin terminations. Its dimensions are 17.50 mm in length, 5.50 mm in width, and 12.00 mm in height. The operating temperature range is -40°C to 85°C, making it suitable for a wide variety of environments.</p><p>&nbsp;</p><p>Typical applications include DC filtering, coupling, decoupling, and snubber circuits where reliable performance and long life are required. The self-healing characteristic of metallized film capacitors helps prevent catastrophic failure in the event of voltage spikes or overstress.</p>
