IDC Low Inductance Capacitors (RoHS) IDC (InterDigitated Capacitors) 0306/0612/0508 GENERAL DESCRIPTION Inter-Digitated Capacitors (IDCs) are used for both semiconductor package and board level decoupling. The equivalent series inductance (ESL) of a single capacitor or an array of capacitors in parallel determines the response time of 0612 a Power Delivery Network (PDN). The lower the ESL of a PDN, the faster the response time. A designer can use many standard MLCCs in parallel to reduce + + ESL or a low ESL Inter-Digitated Capacitor (IDC) device. These IDC devices are available in versions with a maximum height of 0.95mm or 0.55mm. IDCs are typically used on packages of semiconductor products with power levels of 15 watts or greater. Inter-Digitated Capacitors are used on CPU, GPU, 0508 ASIC, and ASSP devices produced on 0.13, 90nm, 65nm, and 45nm processes. IDC devices are used on both ceramic and organic package substrates. These low ESL surface mount capacitors can be placed on the bottom side or the top side of a package substrate. The low profile 0.55mm maximum height IDCs can easily be used on the bottom side of BGA packages or on the die side of 0306 packages under a heat spreader. IDCs are used for board level decoupling of systems with speeds of 300MHz or greater. Low ESL IDCs free up valuable board space by reducing the number of capacitors required versus standard MLCCs. There are additional benefits to TYPICAL IMPEDANCE reducing the number of capacitors beyond saving board space including higher 10 reliability from a reduction in the number of components and lower placement costs based on the need for fewer capacitors. MLCC 1206 1 The Inter-Digitated Capacitor (IDC) technology was developed by AVX. This is LICC 0612 the second family of Low Inductance MLCC products created by AVX. IDCs are 0.1 a cost effective alternative to AVXs first generation low ESL family for high- IDC 0612 reliability applications known as LICA (Low Inductance Chip Array). 0.01 AVX IDC products are available with a lead-free finish of plated Nickel/Tin. 0.001 1 10 100 1000 Frequency (MHz) HOW TO ORDER W 3 L 1 6 D 225 M A T 3 A Capacitance Style IDC Low Number Voltage Dielectric Capacitance Failure Packaging Thickness Termination Inductance Tolerance Available Max.
