Enhancing Electronic Detonation Systems with Vishay’s TANTAMOUNT Solid Tantalum Chip Capacitors: A Robust Design for Reliable Performance in Harsh Environments

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 tough conditions.

Vishay Intertechnology, Inc. has released 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 feature a strong mechanical design, low leakage current, and undergo rigorous testing to ensure improved performance and reliability compared to standard tantalum capacitors and MLCCs.

The capacitors released today have low DCL values of 0.005CV and a high energy density of tantalum, making them efficient for providing the necessary energy for ignition. This makes them well-suited for remote detonation systems in mining and demolition applications that require reliable discharge. The use of tantalum anode technology and Vishay's high-quality dielectric formation ensures consistent electrical performance in challenging environments.

In order to guarantee dependability, TX3 series capacitors undergo more rigorous testing compared to typical commercial capacitors. Each unit is tested for surge current at 100% capacity using standard screening methods, and also undergoes two additional screenings to ensure consistent electrical performance across different production lots. These capacitors have a durable design, with the capacitive element and lead frame protected by a hard plastic resin. They have higher resistance to shock (100 g) and vibration (20 g) compared to MLCCs, meeting MIL-STD-202 standards.

The TX3 series is available in two different case sizes, B and C, with capacitance ranging from 10 µF to 100 µF and voltage ratings from 16 V to 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 +25 °C, a ripple current of up to 0.438 A, and can operate at high temperatures up to +125 °C. They have lead (Pb)-free terminations and comply with RoHS standards, are halogen-free, and are considered Vishay Green.

You can now get samples and production quantities of the latest solid tantalum capacitors, but they may take 10 to 12 weeks to be delivered. To find out the prices, reach out to your nearby Vishay representative.
