Enhancing Electronic Detonation Systems with Vishay’s 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 tough conditions.
Vishay Intertechnology, Inc. has launched 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 mechanical design, low leakage current, and undergo strict testing to ensure improved performance and reliability compared to standard tantalum capacitors and MLCCs.
The capacitors that were introduced today have a low DCL value of 0.005CV and utilize tantalum, which has a high energy density compared to other capacitor technologies. This allows the capacitors to provide more energy for reliable ignition, making them well-suited for remote detonation systems in mining and demolition settings. The tantalum anode technology in the devices, along with Vishay's superior dielectric formation, ensures consistent electrical performance even in harsh conditions.
In order to guarantee reliability, TX3 series capacitors undergo more rigorous testing compared to regular commercial capacitors. Each capacitor is tested for surge current using standard methods, and also undergoes two additional screenings to ensure consistent electrical characteristics across different production lots. These capacitors are protected by a hard plastic resin that encapsulates both the capacitive element and lead frame, providing a durable solution. They have higher shock (100 g) and vibration (20 g) resistance compared to MLCCs, meeting the standards set by MIL-STD-202.
The TX3 series is available in two different case sizes, B and C, and offers a capacitance range from 10 µF to 100 µF with voltage ratings from 16 V to 25 V. The devices have a capacitance tolerance of ± 10%, ESR 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 and are RoHS-compliant, halogen-free, and Vishay Green.
You can now obtain samples and production quantities of the latest solid tantalum capacitors, but there is a lead time of 10 to 12 weeks. To get pricing information, reach out to your Vishay representative in your area.
