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, as well as 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 intended for use in electronic detonation systems. These capacitors in the Vishay Sprague TX3 series are built with a strong mechanical design, low leakage current, and strict testing standards, providing improved performance and reliability compared to regular tantalum capacitors and MLCCs.
The capacitors released today have a low DCL value of 0.005CV and a high energy density compared to other types of capacitors. This allows them to provide more energy for reliable ignition, making them well-suited for remote detonation systems in mining and demolition. The use of tantalum anode technology and Vishay's superior dielectric formation ensures consistent electrical performance in challenging environments.
In order to guarantee reliability, TX3 series capacitors undergo more rigorous testing than standard commercial capacitors. Each component is subjected to surge current testing following standard screening methods, as well as two extra screenings to ensure consistent electrical characteristics across production lots. These capacitors are encased in hard plastic resin for added durability, providing a strong solution. Additionally, they offer higher shock resistance (100 g) and vibration tolerance (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 be 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 of up to +125 °C. The TX3 series features lead (Pb)-free terminations and is compliant with RoHS, halogen-free, and Vishay Green standards.
You can currently request samples and order production quantities of the recently released solid tantalum capacitors, but be aware that there is a lead time of 10 to 12 weeks. To inquire about pricing, reach out to your nearest Vishay representative.
