Enhancing Electronic Detonation Systems with Vishay’s TANTAMOUNT Solid Tantalum Chip Capacitors: Robust Design and Stringent Testing Specifications for Reliable Performance in Harsh Environments
Vishay's solid tantalum chip capacitors are designed to improve the performance of electronic detonation systems. TANTAMOUNT devices have a strong design, low 0.005CV DCL, and undergo strict testing to ensure reliable detonation in tough conditions.
Vishay Intertechnology, Inc. has released a new line of TANTAMOUNT surface-mount solid tantalum molded chip capacitors that are made for electronic detonation systems. The Vishay Sprague TX3 series capacitors have a strong design, low leakage current, and strict testing standards, which results in improved performance and reliability compared to regular tantalum capacitors and MLCCs.
The capacitors released today have low DCL values of 0.005CV and a high energy density compared to other types of capacitors. This allows them to deliver more energy for reliable ignition, making them suitable for use in remote detonation systems for mining and demolition. The use of tantalum anode technology and Vishay's high-quality dielectric formation ensures stable electrical performance in harsh environments.
In order to guarantee reliability, TX3 series capacitors undergo more rigorous testing compared to standard commercial options. Each capacitor is tested for surge current using standard methods and undergoes two additional screenings to ensure consistent electrical characteristics across different production lots. The capacitive element and lead frame of the devices are protected by a tough plastic resin for added durability. These capacitors offer higher resistance to shocks (100 g) and vibrations (20 g) compared to MLCCs, meeting the standards outlined in MIL-STD-202.
The TX3 series is available in two 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, ripple current up to 0.438 A, and can operate at high temperatures up to +125 °C. They have lead (Pb)-free terminations, are RoHS-compliant, halogen-free, and are part of the Vishay Green initiative.
The new solid tantalum capacitors are currently in stock and available in both small sample sizes and larger production quantities. The lead times for orders are estimated to be between 10 to 12 weeks. If you are interested in pricing information, please reach out to your nearest Vish
