WHAT DIFFERENCE BETWEEN FUSED (VISHAY SPRAGUE 893D) STANDARD, NON-FUSED (VISHAY SPRAGUE 293D 593D) TANTALUM CAPACITOR?
893D series designed operate high-current applications employs "electronic" fusing mechanism. "electronic" fuse activation time based heating therefore dependent fuse length (fuse length determines fuse resistance) available current. This type fuse ideal high-current applications, suitable low-current applications. fusing activation indicates, fusing time increases significantly when available current below approximately 893D fuse will "open" below because below energy required activate fuse. Between fuse will eventually activate, some capacitor circuit board "charring" occur. summary, 893D capacitors ideal high-current circuits where capacitor "failure" cause system failure. Type 893D capacitors will prevent capacitor circuit board "charring" usually prevent circuit interruption that associated with capacitor failure. "shorted" capacitor across power source cause current and/or voltage transients that trigger system shutdown. 893D fuse activation time sufficiently fast most instances eliminate excessive current drain voltage swings. 893D series designed operate circuits with external series resistance. 893D series will have failure rate levels equivalent 293D non-fused molded tantalum chip series. 893D series changes failure mode from "short" circuit "open" circuit.

Note Moisture sensitivity levels test conditions assure capability were developed semiconductor industry, surface mount devices that susceptible `popcorn' phenomenon. Passive component manufacturers, including solid tantalum capacitors, have done some preliminary investigation regarding moisture sensitivity have adopted J-STD-020C standard offered alternative this time. Type 195D, 572D, 591D, 592D, 594D, 595D, 597D, T95, T96, T97, 695D conformal-coated capacitors vacuum packaged metallized bags meet moisture sensitivity level rating (MSL) respectively, specified J-STD-020C. unused capacitors should resealed metallized with fresh desiccant. moisture strip (Humidity Indicator Card) included assure dryness. excess moisture remains, capacitors dried (standard "drybox" conditions). However, avoid this type issue, advised these capacitors within Floor Life specified.
WHAT SHELF LIFE SOLID TANTALUM CAPACITOR?
Solid tantalum capacitors stable with time, with known wear-out mechanism. Aside from solderability concerns with unmounted capacitors, solid tantalum capacitors have restrictions with standard shelf conditions maximum, RH). After 1999/2000 timeframe, demand tantalum capacitors dropped sharply, resulting high inventory levels capacitors that exceeded standard year date code restriction. Vishay instituted solderability testing program that showed excellent solderability capacitors years. solderability test hour steam test ANSI/J-002, MIL-STD-202, Method 208.

CAN'T THIS RATED CAPACITOR USING POWER SUPPLY?
Tantalum capacitors require proper derating order operate properly within customer's application. This been established many years since military acceptance tantalum's late 1950's, which lead establishing standard life test procedures. That being, operation rated voltage 1000 using current limiting resistor series. This "steady state" test procedure still industry standard today. level exponential failure rates were 1000 Standard military commercial product designed meet this failure rate requirement. Now, impedance circuitry (minimal current limiting resistance) requires better than failure rates. Thus, voltage derating greatly enhances reliability. field failure rate data became available, mostly though military studies, actual reliability calculations became possible. Hence, Mil-Std-217 developed capacitors types. Derating applied voltage from full rated voltage down dropped field failure rates approximately
