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. The TANTAMOUNT devices have a strong design and low 0.005CV DCL, along with strict testing standards to guarantee dependable detonation in challenging conditions.

Vishay Intertechnology, Inc. has released a new line of surface-mount solid tantalum molded chip capacitors that are tailored for electronic detonation systems. The Vishay Sprague TX3 series capacitors have 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 that were launched today have low DCL values of 0.005CV and a high energy density compared to other types of capacitors. This means they can provide more energy for ignition, making them suitable for remote detonation systems in mining and demolition settings. The use of tantalum anode technology and Vishay's high-quality dielectric formation guarantees stable electrical performance in challenging conditions.

In order to guarantee dependability, TX3 series capacitors undergo more rigorous testing compared to typical commercial capacitors. Each component is subjected to 100% surge current testing using standard methods, as well as two extra screenings to ensure consistent electrical performance across different production batches. These capacitors are designed with a durable construction, with the capacitive element and lead frame encased in hard plastic resin. They have superior shock and vibration resistance (100g and 20g respectively) in compliance with MIL-STD-202, outperforming MLCCs in this aspect.

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

You can now request samples and order production quantities of the latest solid tantalum capacitors, with a waiting time of 10 to 12 weeks. To inquire about pricing, reach out to your nearby Vishay representative.
