Enhancing Electronic Detonation Systems with Vishay’s TANTAMOUNT Solid Tantalum Chip Capacitors
Vishay's Solid Tantalum Chip Capacitors improve the performance of electronic detonation systems. TANTAMOUNT devices are designed to be strong and have low 0.005CV DCL, along with strict testing requirements to ensure dependable detonation in tough conditions.
Vishay Intertechnology, Inc. has released a new line of surface-mount solid tantalum molded chip capacitors that are intended for use in electronic detonation systems. The Vishay Sprague TX3 series capacitors are designed with a strong mechanical structure, low leakage current, and rigorous testing standards to provide improved performance and reliability compared to standard tantalum capacitors and MLCCs.
The capacitors being introduced today have a low DCL value of 0.005CV and a high energy density compared to other types of capacitors. This means that they can deliver more energy for reliable ignition, making them well-suited for remote detonation systems used in mining and demolition. The capacitors use tantalum anode technology and Vishay's high-quality dielectric formation to maintain stable electrical performance in tough conditions.
TX3 series capacitors undergo more rigorous testing compared to standard commercial capacitors to ensure their reliability. Each capacitor is subjected to 100% surge current testing using standard methods, and also undergoes two additional screenings to eliminate variations between production lots. These capacitors are designed with a robust solution, as their capacitive element and lead frame are protected by hard plastic resin. In comparison to MLCCs, TX3 series capacitors have higher shock (100 g) and vibration (20 g) capabilities that adhere to MIL-STD-202 standards.
The TX3 series is available in two case sizes, B (EIA 3528-21) and C (EIA 6032-28), and offers a capacitance range of 10 µF to 100 µF with voltage ratings between 16 V and 25 V. The capacitance tolerance can go as low as ± 10%. These devices have ESR values ranging from 0.700 Ω to 2.3 Ω at a temperature of +25 °C, with a ripple current of up to 0.438 A and can operate at high temperatures up to +125 °C. They come with lead (Pb)-free terminations, are RoHS-compliant, halogen-free, and are considered Vishay Green.
You can now get samples and larger quantities of the new solid tantalum capacitors, but be prepared for a wait of 10 to 12 weeks. To find out about pricing, reach out to a Vishay representative in your area.
