B.3 ACCESSORY BAG BOM
The BOM in Table B-5 corresponds to the collection of resistors, capacitors, and
MCP6271 op amps that comes in the Accessory Bag which is shipped in the Active
Filter Demo Board Kit. It includes enough op amps and jumpers to support any
reasonable filter design. It also supports the circuit in ”Chapter 3. “Building the Filter
Supplied in the Kit”. Other filters may need tighter tolerance resistors and capacitors
(i.e., 1% or 2%). The customer provides the resistors and capacitors for any other filter
circuit.

Note 1: Four of these “resistors” (jumpers) are used for shorting the feedback resistors (Z
1
on 3 PCBs), and for shorting Z
11
on the SK-LP1 stage (see Table 3-1), for the filter
in
”Chapter 3. “Building the Filter Supplied in the Kit”. A total of ten is
included because this is the maximum that might be needed for any FilterLab
design, plus two spares.
2: These five op amps are placed in ESD protective “clam shells,” which are then put
into an ESD protective bag with the resistors and capacitors.
