Enhancing Electronic Detonation Systems with Vishay’s Robust TANTAMOUNT Solid Tantalum Chip Capacitors

Vishay's solid tantalum chip capacitors improve the performance of electronic detonation systems. TANTAMOUNT devices have a strong design and low 0.005CV DCL, along with strict testing requirements to guarantee dependable detonation in challenging conditions.

Vishay Intertechnology, Inc. has unveiled a new line of TANTAMOUNT surface-mount solid tantalum molded chip capacitors that are tailored for use in electronic detonation systems. The Vishay Sprague TX3 series capacitors have a strong mechanical design, low leakage current (DCL), and rigorous testing standards, providing improved performance and reliability compared to standard tantalum capacitors and MLCCs.

The capacitors that were released today have a low DCL value of 0.005CV and a high energy density due to tantalum, making them ideal for providing the necessary energy for proper ignition. This makes them well-suited for use in remote detonation systems that require reliable discharge in mining and demolition settings. The tantalum anode technology and high-quality dielectric formation from Vishay ensure consistent electrical performance even in tough conditions.

In order to guarantee reliability, TX3 series capacitors undergo more rigorous testing than typical commercial capacitors. Each capacitor is tested for surge current using standard methods, as well as undergoing two additional screenings to ensure consistent electrical characteristics across different production lots. These capacitors are designed with a durable encapsulation of hard plastic resin to protect the capacitive element and lead frame. Compared to MLCCs, they have higher tolerance for shock (100 g) and vibration (20 g) as per MIL-STD-202 standards.

The TX3 series is available in two case sizes, B (EIA 3528-21) and C (EIA 6032-28), offering 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 an ESR ranging from 0.700 Ω to 2.3 Ω at +25 °C, a ripple current 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 labeled as Vishay Green.

You can now request samples and order production quantities of the recently released solid tantalum capacitors. It will take approximately 10 to 12 weeks for your order to be fulfilled. If you would like information on pricing, please reach out to a Vishay representative in your area
