IDC Low Inductance Capacitors (RoHS) 0306/0612/0508 IDC (InterDigitated Capacitors) 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 0612 parallel determines the response time of 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. 0508 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, 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 0306 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 TYPICAL IMPEDANCE packages or on the die side of packages under a heat spreader. 10 IDCs are used for board level decoupling of systems with speeds of MLCC 1206 300MHz or greater. Low ESL IDCs free up valuable board space by 1 reducing the number of capacitors required versus standard LICC 0612 MLCCs. There are additional benefits to reducing the number of 0.1 capacitors beyond saving board space including higher reliability IDC 0612 from a reduction in the number of components and lower 0.01 placement costs based on the need for fewer capacitors. The Inter-Digitated Capacitor (IDC) technology was developed by 0.001 AVX. This is the second family of Low Inductance MLCC products 1 10 100 1000 Frequency (MHz) created by AVX. IDCs are a cost effective alternative to AVXs first generation low ESL family for high-reliability applications known as LICA (Low Inductance Chip Array). AVX IDC products are available with a lead-free finish of plated Nickel/Tin.
